OK not travel but viewing into the future, then making decisions in the present based on future knowledge.

My 7/10 is generous, I know, but that's for what the filmmakers achieved at the budget point and for a compelling idea. Historical future fiction is a weakness of mine, and whilst this isn't Azimov, it manages to get the time travel aspects "right" in-universe. Nothing annoys me more than a film which sets up rules then breaks them.

Another (very different) modest budget British time travel film which gets its timeline "right" which viewers may wish to try is "Frequently Asked Questions About Time Travel".
